You multiply 28, 60, and 29.50 individually by 0.07 for the taxes: 1.96, 4.20 and 2.065. (I rounded 2.065 to 2.10). Then add together the totals of the shirt, jeans and cologne and the tax total to get $125.76. Written out: 28 + 60 + 29.50 + 1.96 + 4.20 + 2.10= $125.76. This is just my answer based on my best knowledge. Hope it helps!
